Abrasion testing is done by rubbing a fabric to determine how long the fabric will last before showing wear. The higher the rub count, the longer it will last. There are two standard methods of testing: Wyzenbeek and Martindale. Look for the terms Double Rubs or DR. Typically when a fabric is an upholstery fabric it will always have a double rub rating, however some drapery fabrics will also show a double rub test rating which are typically in the range of 10,000 or less.
The Wyzenbeek double rub test is a back and forth rub while the Martindale test rubs in a figure eight pattern. The higher the double rub test rating the longer the fabric will last.
